Hi,
From your description of your partners boils, I do not think you need to worry about AIDS.
The HIV virus that causes AIDS suppresses the immune system of the body making it vulnerable to various infections. These infections cannot be treated easily as the body is too weak to fight them. You have said that your partners boils go away within the week - this would not have happened if she had had the virus. The boils would have increased in size and become more severe and would have needed high dose antibiotics to go away.
I suspect that she has been sweating a lot ever since she put on weight. This sweat blocks the pores of the skin leading to the formation of pus filled boils.
Since she is 2 weeks late with her period, perhaps it would be better to get a pregnancy test.
Since you have been 2 and a half years together without any other signs of AIDS (e.g. sudden loss of weight, acute diarrhoea, chronic cough or sore throat etc.) I do not believe either of you are suffering from AIDS.
I hope this helps.
